Which measure is used to assess the quality of distractors in test questions?

• A. Needs Analysis Function
• B. Sequential Task Analysis
• C. Certification Tool
• D. Quality Measure

Answer: (D)

In item analysis, the measure used to gauge how well the incorrect options perform is a quality measure. A good distractor is plausible enough to attract respondents who don’t know the correct answer, helping to separate those who understand the material from those who don’t. By examining how often each option is chosen, you can identify distractors that are too obvious or too weak. If a distractor is rarely selected, it isn’t functioning as a true distractor and should be revised or replaced. If a distractor draws too many responses from knowledgeable test-takers, that can indicate ambiguity or overlap with the correct answer, signaling a need to adjust the item. The goal is to maintain distractors that are credible alternatives, which sharpens the overall quality of the question and the assessment. The other terms relate to different aspects of training design and certification, not to evaluating how well the wrong answers work.
